jruby/rack/rails truncating post data when submitting data

[stewartmckee]

Hi,

I am having a problem with post data being truncated at around 5k from
a form running jruby 1.3.1 on rails 2.3.3 with warbler and jboss.  I
have posted the firebug copy of the post and the output from rails for
the same post.

Browser - http://pastebin.com/m4803285d
Rails - http://pastebin.com/m75ae239c

Firstly the content param has been truncated, but also strangely, what appears to be the remainder of the params also have been lost (_method, name), so sounds like its before it parses the post body that the issue is appearing.

I have looked at request.raw_post and that also has been truncated.

I noticed that there was an issue a while back but seemed to get fixed in jruby 1.1.  I've also tried it on 1.4 RC1 and get the same issue.

Has anyone seen anything similar, or can point me in the right direction to debug this as i seem to have exhausted my google foo?

I've had a quick look at Rack, and suspect that this is where the problem lies, and intend to investigate further there, but if anyone has seen this before or can think of where in Rack it might be i would appreciate the help.

thanks,
Stewart.

Found the issue, turned out we were using a nightly build of rack (jruby-rack-0.9.5-20090625.190033-5.jar) rather than the stable release (jruby-rack-0.9.5.jar).  Works like a charm now!
